464 39% Off**
As an experienced outdoorsman and tactical gear specialist, I’ve handled countless ammunition types, but the Underwood Ammo .458 HAM’R 300 Grain Jacketed Hollow Point Brass Cased Rifle Ammunition
464 39% Off immediately caught my attention due to its hard-hitting reputation and specialized application. Manufactured by Underwood Ammo, this round is engineered for impressive stopping power, making it a serious contender for hunting and potentially defensive scenarios within its effective range.
I was looking for ammunition that could reliably take down larger game within 200 yards from an AR platform rifle. Specifically, I was seeking a cartridge with significant terminal ballistics compared to the standard 5.56 or even 300 Blackout.
The initial unboxing revealed meticulously packaged rounds, seated in new, shiny brass. The jacketed hollow point bullets appeared flawlessly formed and uniform, inspiring confidence in their potential performance. Compared to standard .45-70 Gov’t rounds I’ve used in lever actions, the .458 HAM’R feels significantly shorter and more compact, tailored for the AR-15 platform.
I initially considered the 450 Bushmaster, but the .458 HAM’R’s flatter trajectory and higher velocity appealed to me based on my hunting needs. I was excited to see if the Underwood Ammo offering could live up to the claims of exceptional accuracy and terminal performance.

464 39% Off** to the Test
First Use Experience
My initial testing of the Underwood Ammo .458 HAM’R 300 Grain Jacketed Hollow Point Brass Cased Rifle Ammunition
464 39% Off took place at my local shooting range, an outdoor facility with distances up to 300 yards. The weather was clear and sunny, with a slight breeze, providing optimal conditions for accuracy testing. I used an AR-15 pistol with a 12.5-inch barrel specifically chambered in .458 HAM’R.
The recoil was definitely more substantial than standard AR-15 rounds, but manageable. Muzzle rise was noticeable but predictable, and the rifle cycled reliably without any malfunctions in the first 60 rounds.
The initial impression was overwhelmingly positive – the ammunition consistently grouped within 1.5 inches at 100 yards, exceeding my expectations for such a large-bore cartridge in an AR platform.
Extended Use & Reliability
After several months of use, the Underwood Ammo .458 HAM’R 300 Grain Jacketed Hollow Point Brass Cased Rifle Ammunition
464 39% Off continues to perform admirably. I have put over 200 rounds through my rifle now, and experienced zero malfunctions. The brass shows no signs of excessive wear after firing, indicating proper chamber pressure for my firearm.
I’ve primarily used this ammunition for target practice and accuracy drills, but I did take it on a hog hunt. While I didn’t harvest anything on that particular trip, the round’s potential stopping power instilled considerable confidence.
Compared to the .300 Blackout rounds I previously used for hog hunting, the .458 HAM’R offers a significantly greater margin of error due to its superior kinetic energy and potentially larger wound cavity. Cleaning the rifle after firing these rounds is standard; however, the Underwood Ammo seems to burn relatively cleanly, minimizing fouling.
